N = (3.2 * 10^p) * (4.5*10^q) where p and q are integers. Express N in terms of p and q. Give your answer in standard form How? I tried 14.4 * 10^(p+q) but that is not right.

I tried 14.4 * 10^(p+q) but that is not right. Do you mean the standard form of scientific notation? If so I would use $\displaystyle N = 1.44 \cdot 10^{1+p+q}$
why 1 + p + q, where do you get the +1
